Image processing device and an image processing method of correction of front end fading or sweepup adapted to the state of thinning |
摘要 |
Provided is an image processing device including: an outline detection unit which analyzes image data to detect an outer edge pixel forming the outline of image, and to determine an edge direction of the outer edge pixel; a thinning unit which processes thinning by reducing a pixel value of the outer edge pixel; and an outline adjusting unit. The outline adjusting unit determines a correction value of front end fading to be adopted to the outer edge pixel, depending on sheet-feeding direction when the image data is printed and the edge direction of the outer edge pixel; reduces the correction value of front end fading, depending on the ratio of reduction by the thinning of the pixel value of the outer edge pixel; and corrects the front end fading by adding the reduced correction value to the pixel value of the outer edge pixel. |
